You could load the image into an ImageIcon

And then you need to tell the table that you have icons in the column so it can choose the apppriate renderer (the default renderer will simply use the toString() method of the Object). Simple example:

Why do I even bother to answer when people can't even take the time to read the suggestion?

[url http://java.sun.com/docs/books/tutorial/uiswing/components/icon.html]How to Use Icons[/url]. First learn how to load an image into your program using a JLabel. Once you've mastered that then move on to displaying the icon in a table.

Come on buddy. WAKE UP!

What you said (note the part in bold!) "I loaded the image into an imageIcon but in Jtable appears like a string"

What camickr said in the post that you said that you read but obviously did not (again note part in bold) "And then you need to tell the table that you have icons in the column so it can choose the apppriate renderer (the default renderer will simply use the toString() method of the Object). "

So you want to try that one again?

hi,one thing i can suggest and that never fails, you write your own renderer for that column. i hope you understand, if not then please get back i will try to elaborate more.regardsAniruddha

Hi :) Try implementing your own TableCellRenderer which displays your

image from the database, and set it as the renderer for the appropriate

column in your table.

Table table = new JTable(tableModel);

TableColumnModel tcm = table.getColumnModel( );

TableColumn columnThatDisplaysImage = tcm.getColumn(tableModel.COLUMN);

columnThatDisplaysImage.setCellRenderer(new yourImplementationOfTheRenderer( ));

You where given a working example. Run that code. Understand that code and then fix your code. We can't tell you whats wrong based on the few "unformatted" lines of code you posted.

> Try implementing your own TableCellRenderer

> you write your own renderer for that column

Why would you want to write your own renderer when its already suppported by the table? Is that not extra work? If the OP can't copy code from a working 10 line program, why would you think they can understand the concepts of writing a custom renderer?

If your comment is about assigning the renderer directly to the column instead of overriding the getColumnClass() method, then there is still no reason to write a custom renderer. You can use the table.getDefaultRenderer(...) method to get the renderer and then assign the renderer to the column.
